Njengezingxenye ezincane ezisele zemikhiqizo eminingi, imishini kanye nemishini, izimpawu zidlala indima ebalulekile.Uma ukhetha uphawu olungalungile, umshini wonke ungase ulimale.Kubalulekile ukwazi uhlobo ngalunye lwezimpawu zeqiniso uma ufuna ukusebenzisa ezifanele.Ngakho-ke ungathola usayizi olungile wophawu olunama-seal abalulekile asuselwa kusilinda owusebenzisile.
Ungakhetha kanjani uphawu olufanele?Sicela ugxile ekwakhiweni kophawu nasekukhetheni izinto.
Into yokuqala izinga lokushisa, ezinye izinto zingasetshenziswa ezimweni zokushisa eziphakeme kakhulu, ezinye azikwazi.Isibonelo, izinga lokushisa lokusetshenziswa kophawu lwe-PU lisuka ku--35 kuya ku-+100 degree, izinga lokushisa lokusetshenziswa kophawu lwe-NBR lisuka ku--30 Celsius kuya ku-+100 degrees Celsius, izinga lokushisa lokusetshenziswa kwe-viton material seal lisuka ku -25 I-Celsius degree kuya ku-+300 Celsius degree.Ngakho ukumelana lokushisa in ezahlukene impahla seal ihlukile.
Isici sesibili yizimo zokucindezela, ezinye izimpawu azikwazi ukusebenza esimweni sokucindezela okuphezulu.Udinga ukwazi ububanzi bengcindezi yesistimu yoketshezi olusebenzayo, kanye nemvamisa nokuqina kweziqongo zengcindezi.Ezinhlelweni eziningi, udinga ukwazi isidingo sophawu ngaphansi kwengcindezi ekhonkolo.
Isici sesithathu uketshezi kanye ne-viscosity esetshenziswa ohlelweni, izimpawu esizisebenzisile zidinga ukumelana noketshezi noma zivimbele ukudlula uketshezi.Kudingeka sihlole ukuthi imidiya isekelwe kuwoyela wamaminerali noma isekelwe emanzini.
Ngakho-ke ngaphambi kokukhetha into ethile noma uhlobo lophawu, qiniseka ukuthi wazi kahle ukuthi iluphi uketshezi oluzoba khona ohlelweni, izinga lokushisa elingase libe khona, nokuthi ingakanani ingcindezi engase ibe khona.
Ngaphandle kwalokho, udinga ukwazi ubukhulu bophawu noma ububanzi be-piston yenduku, usayizi we-groove njll, kanye nokusetshenziswa kwesilinda nakho kubalulekile.
Ingabe unemibuzo mayelana nokucaciswa okuhlukile kwesixazululo sakho sokutywinwa?Sicela usithinte, ama-INDEL seals azokunikeza isiqondiso sochwepheshe.
